IMPROVEMENT lN STEAM-JET PUMPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be itknown that we, ALBERT J. BLAKSLEE and GARNER O.-WIL1;IAMs, of Du Quoin, in the county of Perry and State of Illinois, have invented an Improvement in Steam-jet Pumps and we do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawing making part of this specification, in which- Figure 1 is an external view of the pump.

Figure 2 is a diumetrical section through the same.

Figure 3 is a bottom view of fig. 1.

Figure 4 is a top yiew of 'fig. 1.

Similar letters 'of reference indicate corresponding parts in the several figures.

This invention relates to that class of steam-pumps wherein theflowof a column of water through the pump is produced bythe direct action of a column or jet of steam. v

The nature of our invention consists in the introduction of a stem within the steam-nozzle and the combining passage of the pump in such manner that the volumes of steam and water are more intimately and rapidly blended in said combining chamber, as will be hereinafter explained.

\Ve are aware that in the year 1862, \V. XV. Marsh obtained Letters Patent on a method of raising water by steam, wherein be employed a cone in such man nor as to spread the steam as it issued into the water-passage, and facilitate the expulsion of air from said passage.

We do not claim eitherthc use of -the s teanr-jet or the cone as our invention.

To enable others skilled in the art "to-uudorstalnl our invention, we will describe its construction and operation.

In the accompanying drawing we have represented only-those parts-of the pump which are'uecessa-ry to illustrate the invention herein claimed. Other parts of the pump maybe constructed in the usual wellknoun manner, or in any other suitable manner.

.Vc will further state that the device which we are about to describe may be duplicated at one or more points int-he delivery-pipe, upon the principle set forth in our Letters Patent numbered 91,205.

A represents a T-shapcd connection or socket,

adapted for having screwed into it three pipes, to wit: the steam inlet-pipe O, the delivery-pipe B, and the water inlet-pipe, which latter is screwed into the socket a.

The upper end of the steam-pipe O terminates in a contracted conical nozzle or jet Ii, which is centrally within the body of the .portion A, and the axis of which coincides with the axis of the delivery-pipe B.

Directly above or opposite the contracted nose of the nozzle or jet 1), is the combining passage 0', in which the water and steam combine on their way to and through the delivery-pipe.

This passage 0' is made like an inverted funnel, that is to say, with its lower end flaring downwardly, so as to freely receive the volumes of water and steam at the confluence thereof.

1) is a stem or cylindrical rod, which is secured at its lower end to the pipe 0 by a spider, d, or in any other suitable manner.

This stem rises centrally through the nozzle b, the

body of the connection A, and the combining passage 0, and terminates at any' suitable point within or above the latter. 1

This stem 1) displaces the center of the jet 0 steam, and also the center of the water jet in the combining passage, and thus, by producihg two annular ascending columns of wateaand steam, the two will be more mpidly and thoroughly mixed, and bet- (or results will be produced with an ecouomycf steam than can be obtained by two solid columns of stean'r and water, or by a hollow column of steam impinging against a solid column of water.

The discharge-pipe may be of a uniform size throughout, that is to say, its lower portion need not be rcduced, the diameter of the stem D, of course, being made in proper proportions to it.

Having described our invention,

\Vhat we claim as new, and desire to secure by Lettcrs Patent, is I A stem, 1), arranged within the steam and waterpassages, substantially as described.
